These surveillance images released by Little Rock police show a suspect in the April 18 robbery of the Bank of America at 200 W. Capitol Ave.

Authorities have released surveillance images and descriptions from three recent bank robberies in a bid to get tips that will help them make arrests.

In Little Rock, three separate robbers have made off with cash from the US Bank at 5200 Kavanaugh Blvd. on Tuesday, the Bank of America at 8200 Geyer Springs Road on Monday and the Bank of America at 200 W. Capitol Ave. on April 18.

In the most recent robbery, the robber is described as being in his late teens or early 20s and weighing about 130 pounds. He was armed with a black revolver and may have left in a newer-model white truck. US Bank is offering a $10,000 reward for information leading to an arrest and conviction.

In the Monday holdup at the Geyer Springs Bank of America branch, the robber is described as a white man about 45 to 50 years old who stood about 5-foot-11 and weighed about 170 pounds. He had a light gray stubble beard and light gray hair and was wearing a gray-and-black jacket, black shorts, white socks, black shoes, black sunglasses and a black hat. He told the teller he had a gun while holding his waistband, police said.

In the April 18 robbery at the downtown Bank of America, the robber was a black man in his early-to-mid 40s who stood about 5-foot-10 and weighed 175 to 190 pounds. He was wearing a Kangol-style hat, slacks and a tie, and he carried a folio or a brief case. Police say he passed a note to a teller demanding cash and didn't show a weapon.
